You might think labeller or labeler has an obvious answer, but both spellings are correct. The difference comes mainly from the variety of English you are using.
Labeller is the preferred spelling in British English and other varieties that generally follow British spelling conventions. Labeler is the standard American English spelling. Both words refer to a person or machine that labels something.
The good news is that you don’t need to memorize two completely different words. Once you understand the spelling rule behind them, the difference becomes much easier to remember.
Labeller or Labeler: The Quick Answer
Both labeller and labeler are legitimate English spellings.
- Labeller — commonly used in British English.
- Labeler — commonly used in American English.
- Both refer to someone or something that applies a label.
- The difference follows the broader British and American spelling patterns for words ending in -l.
For example:
The factory installed a new labeller to package its products.
In American English, the same sentence would normally use:
The factory installed a new labeler to package its products.
Neither spelling is inherently wrong. The important thing is to use the version that matches your intended variety of English.
What Does Labeller or Labeler Mean?
A labeller or labeler is a person, device, or machine that puts labels on products, packages, documents, or other objects.
The word comes from the verb label, meaning to attach a label to something or to identify something with a particular description.
Depending on the context, a labeller or labeler could be:
- A person who labels products
- A machine that applies product labels
- A worker responsible for identifying packages
- Software that assigns names or categories to data
- A tool used to mark or classify objects
For instance, a food-processing company might use an automated labeler to place labels on thousands of containers each hour.
Labeller vs Labeler: Why Are There Two Spellings?
The difference comes from a spelling convention involving words ending in a consonant followed by -l.
British English often doubles the final l when adding certain suffixes, while American English frequently keeps a single l.
Compare these examples:
| British English | American English |
| labelling | labeling |
| labelled | labeled |
| labeller | labeler |
| travelling | traveling |
| traveller | traveler |
This pattern explains why labeller or labeler can look different while still representing the same word.
The British spelling: Labeller
In British English, labeller is generally preferred.
The spelling follows the convention of doubling the final l before adding a suffix beginning with a vowel.
You will therefore commonly see:
- label → labeller
- label → labelled
- label → labelling
This spelling is also likely to appear in other English varieties influenced by British usage.
The American spelling: Labeler
American English generally uses labeler with one l before the -er ending.
The same convention appears in related forms:
- label → labeler
- label → labeled
- label → labeling
So if you are writing specifically for an American audience, labeler is normally the better choice.
Labeler or Labeller: Which One Should You Use?
The right choice depends on your audience.
Use “labeller” when writing in British English
Choose labeller if your content follows British spelling conventions, particularly when writing for audiences in places such as:
- The United Kingdom
- Ireland
- Australia
- New Zealand
- Other regions that commonly follow British English conventions
However, English usage can vary between countries, so a style guide is always the best authority for professional publications.
Use “labeler” in American English
Choose labeler when writing for an American audience.
This is especially important in:
- American business documents
- U.S. product descriptions
- American technical documentation
- U.S. marketing material
- American academic writing
Consistency matters more than choosing one spelling universally.
Labeller or Labeler for a Machine
The word can describe a machine as well as a person.
For example:
The company purchased an automatic labeller for its bottling line.
An American publication would typically write:
The company purchased an automatic labeler for its bottling line.
In manufacturing, related terms such as labeling machine, label applicator, and automatic labeler are also common.
The exact terminology can depend on the industry and the type of equipment being described.
Labeller or Labeler in Data and Software
The word isn’t limited to physical labels.
In technology, a labeler or labeller can also refer to a person or system that assigns labels to information.
For example, in machine learning, human workers may label images, text, audio, or other data so that an algorithm can learn from correctly classified examples.
You might see phrases such as:
- data labeler
- image labeller
- text labeler
- dataset labeller
- annotation specialist
Again, the spelling usually depends on the English variety used by the organization.
Labelling or Labeling: The Same Spelling Difference
If you understand labelling vs labeling, you’ll find labeller vs labeler much easier.
The same British-American spelling difference appears in all three forms:
- British: labelled, labelling, labeller
- American: labeled, labeling, labeler
This isn’t a difference in pronunciation or meaning. It is primarily a difference in spelling conventions.

Is Labeller or Labeler More Correct?
Neither is universally “more correct.”
Labeller is correct according to British spelling conventions, while labeler is correct according to American spelling conventions.
A common mistake is to assume that one version is a misspelling simply because a particular dictionary or spell-checker prefers the other. Language tools are often configured for a specific regional variety of English.
If your document is set to American English, it may flag labeller. If it is set to British English, it may prefer labeler less often.
The best approach is to choose a regional spelling system and use it consistently.
